What elements contain the same total number of unpaired electrons as potassium?
Elements in the same group as potassium, such as lithium and sodium, also contain one unpaired electron. These elements are in group 1 of the periodic table and have similar electronic configurations.
What type of ions do the elements of group 1 form?
Elements in group 1, also known as the alkali metals, typically form ions with a +1 charge by losing one electron. This is because they have one electron in their outermost energy level, making it easier for them to lose that electron to achieve a stable electronic configuration.
Are group 2 elements highly reactive?
Reactivity increases as you go down the group. Radiom is far more reactive than Beryllium.
Why are group1 and 7 found as compounds?
Group 1 elements have very low electronegativies and group 7 elements have very high electronegativities, so that both are reactive with almost every other element, the group 1 elements by donating electrons and the group 7 elements by accepting electrons.
Oxidation number for first 20 elements?
The oxidation numbers for the first 20 elements in the periodic table are typically as follows: Group 1 elements: +1; Group 2 elements: +2; Group 13 elements: +3; Group 14 elements: +4 or -4; Group 15 elements: -3; Group 16 elements: -2; Group 17 elements: -1; Group 18 elements: 0. Keep in mind that oxidation numbers can vary in different compounds and contexts.
Why are Group 1 and Group 2 elements found in many compounds but not Group 18 elements?
group 18 has completely filled electronic configuration and hence are stable. group 1 and group 2 have 1 and 2 electrons respectively in their valence shells and needs to lose these to attain completely filled electronic configuration. hence they are reactive.

What is happening to the elements electronic structures in group 1?
In Group 1 of the periodic table, the elements have one valence electron. As you move down the group, the size of the atoms increases due to the addition of more energy levels. As a result, the outermost electron becomes further away from the positively charged nucleus and more shielded by inner electrons. Thus, the electronic structure remains similar, with one valence electron, but the atoms become larger in size.
Why size of 18th group elements is larger?
This is because, 1) Inter electronic repulsions between electron pairs present in the outermost orbit. 2) In 18th group elements vanderwaal's radius is considered.

Why hydrogen is placed in group 1 in periodic table although it acts as a halogen also?
Hydrogen is placed in group 1 because it has an electron configuration of 1s1, like other group 1 elements. While hydrogen can sometimes exhibit properties of a halogen, it predominantly displays characteristics of a group 1 element due to its electronic structure and chemical behavior.
What group of elements on the periodic table is most reative?
The alkali metals group, located in Group 1 of the periodic table, is the most reactive group of elements. These elements have one electron in their outermost shell, making them highly reactive as they seek to lose this electron to achieve a stable electronic configuration.
Why are 1st group elements called as unipositive elements?
The alkali metals in group one are called unipositive because each atom allows one electron to move freely through out the bulk of the metal. This is know as the electronic sea. Group two atoms allow two electrons to move freely. The more electrons of each atom that is available for bonding the harder and more dense the structure.
What is another name for alkali metals?
